METALLIC wmoow FRAME AND SASH.

SPECIFICATION forming part of Letters Patent No. 746,477, dated December8, 1903. Application filed June 23, 1903. Serial No. 162,788. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN EBERLE, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Im provements in MetallicWindow- Frames and Sashes Therefor, ofwhich the following is a specification, containing a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to a metallic windowframe and sash therefor; and itconsists in the novel construction hereinafter described and claimed.

The object of my invention is to provide an improved metallicwindow-frame and sash wherein every part will be composed of metalexcept the glass itself.

A further object is to provide a metallic window-frame with improvedmeans whereby stops and parting-strips may be conveniently and quicklyapplied and removed.

In the drawings, Figure 1 is a sectional front elevation of a metallicwindow-frame embodying my invention. Fig. 2 is a vertical centralsection. Fig. 3 is a sectional plan view taken on the line 3 3 of Fig.1-. Fig. 4 is a detail sectional plan view of one side of the frame andsash. Fig. 5 is a perspective view of the parting-strip detached. Fig. 6is a perspective view of one' of the detachable stops.

Fig. 7 is a detail View of the chain-fastener.

1 and 2, respectively, indicate the vertical sides of the frame, whichare preferably of .a single sheet of metal. The left-hand side 1 isproperly bent to form integral stops 3 and 4, the parting-strip 5, andsash-grooves 6 and provided with the usual spacein the rear of same forthe reception of sash-weights 7. The top 8 of the frame is also made ofmetal in the same manner and is suitably secured upon the upper ends ofthe sides 1 and 2. The sill 9 is also made of metal in box form and issuitably connected to the lower ends of the sides in any desired manner.

One of the vertical sides of the frame, preferably-the right-hand side2, as shown, is provided with a removable and adjustable metallicparting-strip 10 and a removable and adjustable metallic inner stop 11.(See Fig. 4.)

Said parting-strip 10 is preferably composed of a single thickness ofmetal having a series of downwardly-inclined slots 12, formed in itsinner edge and terminating at their upper ends in vertical slots 13.

formed to receive said parting-strip and stop.

Said vertical side 2 is formed with a central vertical recess 14 for thereception of the inner edge of said parting-strip 10, and the latter isadjustably retained within said recess by means of bolts 15, which passthrough apertures in the opposite walls of said recess and through theslots 12 and 13, formed, as described, in said parting-strip 10.

The inner stop 11 is adj ustably and removably mounted Within a recess16, formed in the vertical right-hand side 2 of the frame, and said stopis secured in position by means of bolts 17, passing through aperturesformed in the opposite walls of said recess and engaging the slots insaid stop.

18 indicates the lower sash, and 19 the upper sash, both of which aremade of sheet metal, as shown, with proper grooves for the reception ofthe glass.

20 indicates the usual counterbalancechains, which are attached in theusual manner to the Weights 7. I preferably attach said chains to thesash by means of my im proved chain-fastener. (Shown in Figs. 1 and 7.)This fastener preferably consists of a metal loop 21, which is narrowedto fit the chain at its upper end and wider at its lower end. The lowerend of said loop 21 is hinged to the sash by means of a bearing orbracket 22, which is secured to the sash by means of screws or rivets.The upper narrowed end of the said loop is preferably curved outwardly,as shown in Fig. 1, so that said upper end will project a distance fromthe surface of the sash and present a vertical opening for the receptionof the chain. The chain 20 is inserted in said opening formed by thenarrowed upper end of said loop, and then the chain is detachablysecured in position by inserting the pin 23 through one of the links ofthe chain beneath said narrowed portion of the loop, and thiseffectually prevents the Withdrawal of the chain until said pin has beenremoved. It will be observed that the length of the pin is such that itwill be impossible for the same to become accidentally detached.

The operation is as follows: The sash may be readily inserted or removedfrom the window-frame by detaching the parting-strip and stop 11, andthis may be readily accomplished by grasping said strip and stop andsliding the same upwardly until the bolts and 17 are removed from thevertical slots 13 into the inclined slots 12. Said inclined slots willthen offer very little resistance to the inward movement of the saidparts, and they can be readily detached. The upper ends of saidparting-strip and stop Work loosely within suitable openings formed inthe top 8 of the window-frame, as indicated by dotted lines at 24c inFig. 1. After said parting-strip and stop have been detached the sashmay, of course, be readily removed, and the counterbalance-chains 20 maybe readily detached from the sash by withdrawing the fastening-pin 23.

What I claim is-- 1. In a metallic win dow-frame, the vertical sidesformed of sheet metal with an integral fixed parting-strip on one sideand a detachable parting-strip on the opposite side detachablymounted'in a recess, bolts extending across said recess and mounted inapertures formed in the walls of the same, and a sashstop having aseries of inclined slots terminating at their upper ends in verticalslots, and said sash-stop detaohably mounted within another recess inthe frame and having bolts engagingsaid slots, substantiallyasdescribed.

2. In a metallic window-frame, the vertical sides formed of sheet metalwith an integral fixed parting-strip on one side and a detachableparting-strip on the opposite side, detachably mounted in a recess,bolts extending across said recess and mounted in apertures formed inthe walls of the same, and a stop U-shaped in cross-section, and havingpairs of inclined slots terminating at their upper ends in verticalslots, and said stop detachably mounted within a recess with said boltsengaging said slots, substantially as described.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.

JOHN EBERLE.
